This invention relates to new and improved v means and methods of castlng type rurn ture similar machines.

The apparatus'embodying the present inforty-two ems picas when appliedto type I cores are comparativelyfrequently rendered defective during the casting and ejecting g rocess, both by crystallization and'stresses eveloped during the actualcasting of the '15. Y In the space or cavity 27 are, risers 28, 5

casting machines asabove designated, having a melting pot arranged and positioned to in ject molten metal into a slotted mold and against an intermediate plate or closure,

ferred' to are usually constructed in a manner or cavities having side walls,

toprovide slots a bottom or body portion and an upper or cap portion, while the end Walls are formed by two end portions of the'cap-core, so called. i

In the manufacture of the mold parts which are made of steel it is essentialwto harden the metal or at least that portion which forms the moldcavit'y in order to avoid both the adherence of the mold and metalwithin the surface of the cavity and also to resist wear and distortion therein 7 during the ejection of the cast slugs as the? latter are ejectedfrom the mold in the'usual way.

My invention contemplates the production of a uniformly satisfactory. product; i. e. type furniture having the desirable char-:

acteristics of lightness, strength and durabil The moldbody comprising an 7 important feature of my invention has a combination cap-core and a body portionv so constructed as to resist warping, bending,

Additional advantages and objects of invention will appear more fully in the hereinafter specification when taken in connection with the accompan 'ngidrawings in component part of my invention applied to the mold-disk, taken on line 3+3 of Fig. 1.

The cavity 27 of the mold is tapered or beveled transversel while the notches 24 are also tapered from ront to rear, as shown in Figures 6 and 7. By reason of this construction, when molten metal is injected into the cavity, the notches will form transverse strong supports or bridges 28' between the two opposite sides of furniture cast, with cells 29 running from top to bottom of the slug so formed, as best shown in Figure 5.

As an important feature of my invention and as best shown in Figures 1 and2, I provide an intermediate sliding vise-plate or closure 30 which is. supported on the left hand vise-jaw 31 of the slug casting machine by 20 means of an L-shaped clamping extension 32 fastened to the closure and provided with a b81133, impelled by a spring 34, seated on a pin 35, in a passageway 36,-the spring imelled ball servin to maintain the closure in m positionwhi e accomplishing its functions as a stop or closure at the face of the meld during the process of slug casting. When a slu is to be cast, a downwardly extending L-s aped member 37 on the closure 30 proyects. over the right hand vicesjaw 38 and rests against the banking block 39 of the slug casting machine, in this manner eliminating a special bank block which would oth-' erwise be required to take up the difference in height of the mold when the slu-gis ejected. When molten metal under pressure is applied to the rear face of the capscore 20, the metal will flow through the notches 24 and the lower slot 26, filllIl the upper slot25- and the entire cavity 27.. hen the cavity is filled,

the molten metal will abut against the inter-,

mediate plateor closure, a, uniformly accurate sharply defined strong slug being produeed with the bridges or supports; extending from the top to the bottom as described above.

My closure plate whichis approximately onemy novel lowmold is about one-eighth of an inch lower in height than the standard mold,

the closure. for-min apart of this invention being interchangea le to linotype or intertype machines -a feature of great practical advantage.

As best shown in Figures 9 and 10, I provide special means to enable the operator 01"? the slug-casting mach-inc te remove and substitute'one cap-core: for another without the necessity, as hitherto was thecase, of taking labor inactual practice, consists in providing; v

eigihth of inch in thickness makes. up. the i erence in the height: of the standard mold, this being; provided for in my invention as the cap-core 20 and mold body 15 with diagonally positioned registering screw holes I obtained by means of fixed studs or pins 17 which are fastened to the mold body 15 in any suitable way, such as by a drive lit, the

studs or pins 17 entering the notches 40 provided on the ca -core 20 t iereb brin in the cap-core and mold body into alignment longitudinally and transversely.

l/Vith the mold and means described above I am able to cast printers slugs known to the art as head letter or type slugs in addition to furniture by raising the height of the" standard mold and then cutting down proportionally the risers or teeth 28 which form the cells 29 of the slugs- In order to better comprehend the con strnction and mode of operation of my invention, those parts of the assembly of a slugcasting machine to which the apparatus eni bodvin m invention is immediatel a 3- V e y .7 plied, and as lllustrated in Figures 1, 2, 3 and 4, will be described briefly: V

The lefthand vise jaw 31, is slidably mounted on the vise j aw table frame 41, by

means of a shoe60, which has a vertical rail 61, in a groove 62 of the vise-cap 42, as best shown in Figure 4. It will now be readily understood that the L-shaped member 32 of the intermediate vise plate 30 is slidably seated on thc'shoe 60.

To remove the intermediateplate 30, the operating screw handles 47 are turned in a counter-clockwise direction, thereby unlocking the vise jaw 41, from the linotype machlne, the jaw swinging towards the ope'rator. r I

Located on the supper surface or the cap 42, is a slot 63, wherein is positioned an adjusting bar 48, which at one end has the usual finger operating lug, and is at the other held in position by the left hand wedge bracket 51, which is secured to the frame 41.

The ju'stification'i od 54 at its outer end abuts g against the left hand vise jaw 31. The rod 54 is locked by a post 50, which latter is lifted into and out of engagement by means of the bar 52 spring held, and secured by means of screws 64..

Mounted on the upper suri'ace of the bar 2 48 is an operating bar 49,0ne end being pro- Vided with the usual finger lug, and the other end with a tension spring which serves to normally hold the bar 49 closed. oper- 11:; end secured to bracket 53. In the bracket 53 I is the justificationrod'5'4, which is normally the cap-core and ation the bar 49 is moved to the right, thereby raising the bar 52 and post out of engagement with the justification rod 54. The bars 48 and 49 are moved to the left, carrying rod 54. to the left away from theleft hand vise jaw member 31, the latter being moved by the hand to the left readily permitting the intermediate plate 30 to be removed.

By referring to Figure 3, it will be seen that the mold disk 55 which is of the conventional type, is provided with the usual pockets 56 and the shoulders 56, which latter serve as seats for the special lugs 16 forming a part of my invention, the pockets 56 accommodating mold body. For the operation of the mold disk, the usual mold disk pinion 57 is provided. By inspection of the mold disk 55, it will be seen that the'mold body 15 is bolted to the disk by the usual bolts 66. Hitherto, as pointed out above, it was necessary when substituting one mold for another to remove both cap and core and the mold body. By the. means above described and illustrated in the drawings, the cap and core may nowbe quickly removed by merely unscrewing the machine bolts 23, thereby permitting the immediate substitution of another cap-core.

While I have described with some degree of particularity a preferred construction and arrangement of the various parts, it will'be understood that the apparatus is susceptible of modification and variation hence I do not wish to be limited to the precise details as set forth, but desire to avail myself of such changes and embodiments as fairly lie within the scope of the appended claims.

What I claim is new and desire to secure by Letters Patent is:
